Alpha A2206 Crown & Drive for 38mm Tube

The Alpha A2206 Crown & Drive is designed for compatible Alpha 30mm tubular motors installed into a 38mm roller tube.

Alpha describes the A2206 as its most common 38mm tube fitting, making it an important option for customers replacing an existing motor or converting a compatible roller blind to motorised operation.

The crown and drive provide the mechanical interface between the tubular motor and the roller tube, allowing the motor to correctly operate the blind.

Most Common 38mm Tube Fitting

The key distinction of the Alpha A2206 is its application with 38mm roller tubes.

Alpha specifically describes the A2206 as:

“Most common 38mm tube fitting.”

This gives customers considerably more information when matching the component than simply knowing that it belongs to Alpha’s 30mm motor accessory range.

However, customers should still check their existing roller tube before ordering.

A nominal 38mm tube measurement alone doesn’t necessarily mean every tube has the same internal profile.

Designed for Alpha 30mm Motors

Alpha categorises the A2206 under its Crowns & Drives for 30mm Motors range.

The 30mm measurement refers to the tubular motor family, while the A2206 allows the compatible motor to interface with the specified 38mm roller tube.

This distinction is important when replacing an existing blind motor.

The motor and roller tube aren’t necessarily the same diameter because the tubular motor sits inside the roller tube.

Matching Your Existing 38mm Roller Tube

If you’re replacing an existing motor, first check the dimensions and profile of your roller tube.

Measure the tube as shown in our Match Your Existing Blind Tube to the Correct Crown & Drive guide.

A clear photograph looking directly into the end of the tube is also useful because it shows the internal profile that the crown and drive need to match.

If the existing crown and drive are still available, photographs of those components can provide additional information.

What Does the Crown & Drive Do?

A tubular motor operates from inside the roller tube.

The drive transfers the rotational movement of the motor to the roller tube, causing the tube and blind to rotate.

The crown forms part of the connection between the motor and tube and works with the compatible tube profile.

These components therefore need to be correctly matched to the roller tube rather than selected solely according to the motor diameter.

Replacement Motor Installations

The Alpha A2206 can be particularly relevant when replacing a motor in an existing compatible roller blind using a 38mm tube.

If the existing tube remains in good condition, matching the new motor with the appropriate crown and drive may allow the existing roller tube to remain in the blind.

The important step is confirming that the A2206 matches the particular tube configuration before ordering.

Check Before Ordering

Alpha identifies the A2206 as its most common 38mm tube fitting, but customers shouldn’t assume that every roller tube measuring approximately 38mm uses exactly the same internal profile.

Before ordering, check:

• Roller tube diameter
• Internal tube profile
• Existing crown and drive where available
• Existing motor information where available

Our matching guide explains what measurements and photographs to provide if you’re uncertain.
